It is increasingly common for exterior concrete wall cladding elements to be monolithically constructed to frame elements to increase the building's strength and stiffness, with special detailing at plastic hinge locations to minimize damage. This study evaluates the effectiveness of this detailing on reducing downtime and injuries in a four-story building. It was found that the expected annual downtime and number of injuries decreased by 35-40% and 45%, respectively, compared to using a bare frame. This demonstrates strong socioeconomic incentives to implement the monolithic detailing.
